Figure 6`is a vertical sectional view through the door opening surrounding one of the doors of the motor vehicleor the like showing in connection therewith in`diagrammatic representation, another embodiment of the invention having a dierent electrical operation.

While, asstated, the device of the invention is designed primarily to be built into vehicle and f the like bodies at the factory, the device may also be marketed as an accessory and installed in vehicle bodies at low cost. f

Referring in detail to the drawings, the numeral 5r generally designates a motor vehicle door, the numeral 6 designating the inside or 85 inward panel which is usually constructed in the form of upholstery. The numeral 7 indicates the usual window opening and the numeral 8 designates a conventional form of window glass panel and associated structure which is verti- 'cally mowable in channels in the sides of the window opening 7 and therebelow by means of a lever 9 which is pivoted at one end as indicated at 10 at one side of the door and has its' opposite end pivotally and slidably engaged with a slot 95 at the lower edge of the panel, the lever 9 being Y providedl with `an=arcuate slot provided with the teeth l1. A pinion 12'is operated in engagement with the teeth 11 for moving the lever 9 so as to open and close the window 8 by moving the 100 panel downwardly or upwardly in the channels referred to. Y .The hinges of the door are indicated by the numerals 13 and 14, respectively.

It will be observed that the devicev of the invention may be installed vin certaintypes of automobile doors simplyby mounting the motor in the lower'part thereof, drilling a hole in a member corresponding to the housing 37 to receive the upper end of the shaft 28, and mounting the 9 and the operating shaft 25 and its pinion 12, as well as the housing 37, may be already part of the manual window operating mechanism of the doors.

The numeral 15 indicates a lsmall circuit breaker Iwhich is situated within the upper channel of the dooropening'and adapted to be operated by.

contact of the upper edge of window panel 8 'by the window 8 in casing l'lhaving an opening 18 in its top-froxn which depends a `ilangeconstituting a guide for a spring positioned plunger 21 slidable therein. A- dielectric member 20 is carried in the topof the 'casing and supports depending diametrically opvposed spring contacts 19. Theplunger 21 has `a dielectric portion 22, and a conductive portion 1 23 on the lower end for bridging the contacts.

The spring 24 rising fromthe floor of the casing.

normally positions the plunger 21 so that the contacts 19 are bridged by the conductive portion 23 of the plunger, so that a circuit through the spring contacts 19, 19 is normally maintained. This arrangement provides that when the window is not engaged with either ofthe cirl cuit'breakers 15, 16, circuits'l through these circuit breakers are maintained closed. However, when the window panel is movedl to either fully closed or fully open position and intoengagement with either circuit -breaker, the corresponding circuit A will be broken as a result of the'displacement of the plunger for a purpose to be described.

Reference to Figure 2 will disclose that the pinion 12 is carried by the shaft 25't0 which the usual inside manual. window operating handle is connected. Keyed to the shaft 25 within the housing 37' is acomparatively large bevely gear 26. Suitably supported below the '45 bevel gear 2s and in mesh with the bevel gear is a beveled pinion 27 carried on the upper end of asectional shaft 28 rotatably supported at its upper end in the housing 37 and composed of theA l upper section- 29 and the lower section 30 connected for rotation by means oi a sleeve 31 equipped with set screw means 32 to enable disconnection of the sections 29,' 30 of the shaft 28 when desired for repair or likepurposes. This provision enables the man vl operation of the window in the event the power driven mechanism becomes disabled, since the coupling sleeve 31 may in such event be loosened so that the window may be operated with the usual manual means independent of the small electrical motorl 32 which issuitably mounted within the lower part-of the door and has on its shaft a worm 33 which is meshed with a worm gear 34 carried by the lower end portion of the section 30 of the shaft 28. The

lower end of the shaft section 30 may be suitably mounted in a bearing 35. It will vbe obviousthat the end or the shaft 25 to which the manual han#- dle usually employed is to be connected may be covered in' some suitable manner so as to be readily accessible in case of disabling of the power driven window operaton'so that a handle which may be carried in the-automobile atv all times lmay be ready for connection with the shaft 25 for operating the window manually inthe usual In Figure 31s shown a conventional'instrulLaeaeav ment panel 38 upon which is mounted a push button or other type of switch means 39 of a class tobe described. In the drawings six of the controls are shown, this being the number corresponding to-the usual number of windows in a sedan automobile.v A greater or less number vof these may be provided according to the numbery of windows in the different types of motorvehicles or the like. Suitable conductors in an insulated conduit 40 lead from the instrument pan- `el 38 through the body of the vehicle to the battery of the vehicle and to the windows. Where -the windows are located in doors, the conduit 40 is led through the vehicle body and out through theedge of the door opening there- Acuit breakers 15, 16 will be described below. Two

ways of making the connections andI associat ing the related elements are shown herein as illustrative of the invention.

' One way of connecting the elements of the invention, showny in Figure 4, will be described iirst.

'The numeral 41 and the numeral 4 2 refer to small double-pole, double-throw, center position switches, identical with or Yaxley type of these switches. One of the switches 41 is to be located on each door or on the-body of the vehicle adjacent each window, while the switch 42 is to be mounted on the instrurnent panel and is included in the general designation made by the numeral 39. The outside contact members of` the switch 41.are con-v nected to one side of the armature circuit 43 of the motor 32, as shown in the diagram in Figure 4. It will be seen that the lead from one of the 115` outside contact elements has interpolated therein. the circuit breaker 15 while the lead-from the other outside contact element has interpolated therein the other circuit breaker 16. It should be here stated that -boththe eld and the arma- -ture of the motor are series wound. 'I'he other side of the armature circuit of the motor is con-` nected. to a conductor which connects the center stationary contact element of the switch 41, and the center contact in Y movable member 41a of the switch 41 has one side connected to an Ampress device or similar device, by a-conductor 46 and a like connection is made from the Ampress device to the movable member 42a of the switch 42. The remaining 130 side of the Ampress or the like device is connected to the series around ileld 44 of the motor which, in turn, is connected to the conventionalbattery 45 of the vehicle. 4The remaining side of the battery is connected the movable member .i also to the remaining side of the movable member 41a of the switch 41. It will be seen that the tleld ,circuit conductors are designated by the numeral 46 while the armature circuit conduc- 14 tors are designated throughoutthe diagram by the numeral 47.

In Figure 6 is shown a simplified circuit forthe device of our invention, wherein is employed inl stead of the double-pole, of the arrangement shown in Figure 4 there-are employed single-pole, double-throw switches 48, 49. of 'very much simplified character, the use of which requiresl the employment of a suitable magnetically operated comparable to the 105 the switch 42. s The to the remaining side of 42a of the switch 42 and' 'l double-throw switches 141 master switch structure Il such as that generally indicated by the numeral 50. This master switch comprises lan iron armature 51 pivotally supported at its lower end on a suitable pivot bracket 52 and having an insulated cross head 53 on its upper end carrying at its ends contacts 54, 55 for cooperation with pairs of contacts 56, 57 and l58, 59 located on either side f the armature 51. Electro-magnets 60 and 61 .are located on opposite sides of the armature 51 and suitable spring means 62, 63 are connected to opposite sides of the armature for maintaining it in the intermediate, neutral position.

As seen in Figure 6 the circuit breakers 15, 16 are connected together by the conductor 66, and to the contact 57 by means of the conductor 64, and to the contact 58 by the-conductor 65. It will also be observed that the conductor 66 connecting the circuit breakers 15, 16 is connected by means of ya conductor 6'7 to. one side of the armature Acircuit 43 of the motor. The other side of the armature circuit 43 is connected b`y means ofV a conduit 68 to the. contact point 59 of the'magnetic switch, and this is in turn connected to the contact 56 on the opposite side of the switch armature. The contactv 54 on the armature 51 is grounded as indicated at 69 and the remaining contact of the armature 51, namely, the contact 55, is connected by means of the conductor 70 to one side of the ileld circuit 44 of the motor, the other side of the eld 44 be` ing connected by conductors '71v and 72 to the movable contact member 48a of the single-pole, double-throw switch 48 and to the movable-'contact member 49a of the single-pole, double-throw switch 49. A conductor -73 leads from the electro-magnet 60 of the magnetic switch 50 to one of the stationary points of the switch 48, the other side of the electro-magnetl 60 being grounded as indicated at 74. The remaining contactA of the switches 48 and one of the contacts of the switch 49 are connected by means of the conductor 'l5 which has a branch vconnected to one side oi' the remaining electro-mag- .net 61 whose remaining side 23 grounded as indicated at '76. A conductor 77 connects the remaining contact of the switch 49 with the conductor '73.

It will be observed that this circuit is energized by the battery 45 which is grounded as indicated at '17 to the frame of the vehicle or the like, a conductor 78 connecting to the conductor '71 which feeds the eld oi' the motor and the movable contact element oi' the switches 48 and In both forms of the electrical assemblages Just described, the moving of the movable `ele-l r'nents oi' the switches to one side or the other-` will bring about the elevationor the lowering of the window tol which the unit relates. While the connections for these purposes are direct in the form shown in Figure 4, the connections necessary are indirectly made in the form shown in Figure 6. The closing of the switch arms 48a, 49a, with the associated contact points thereof will cause the armature 51 to be swung to either side for making the contacts as described, in one position operating the motor 32 to elevate the window, and in the other position operating the motor to lower the window. It will be obvious that use may be made of the switchmeans generally designated 39 in the form of circuit shown in Figure 4 to control each and any of the win, dows from the drivers seat, or any of the Windows may be operated through utilizing the door or body mounted switches 41, 48.
